  -d {DIR}    a non-existing directory to create repo
  -b {BRANCH} optional: will create BRANCH_NAME repo
  -s {BOARD}  optional: will setup and build BOARD_NAME

  Example:
  To setup a new repo at head on /disk2:
    ./chroot_setup.sh -d /disk2/chromiumos

  To setup at head on /disk2 and build board tidus :
    ./chroot_setup.sh -d /disk2/chromiumos -s tidus

  To setup branch firmware-tidus-6301.109.B on /disk2 and build board tidus :
    ./chroot_setup.sh -d /disk2/firmware-tidus-6301.109.B -b firmware-tidus-6301.109.B -s tidus

  To cleanup branch created in /disk2/chromiumos:
    cd /disk2/chromiumos; cros_sdk --delete
    cd /; sudo rm -rf /disk2/chromiumos
